I'm also experiencing this bug. I use C for sprinting and thus every time I sprint I enter crouch sprint. Fully clearing the bind doesn't seem to fix it. I'm not sure if this happens with other keybinds.
Same bug experience here. I Use to 'c' for class gadget and everytime I use the gadget it toggles crouch. I don't know why they always have these same hardcoded binding issues during every BF beta and usually well into release before they eventually fix it. They also neglected to even make a binding for the class specialization action (its bound to 6 and not changeable).
